Images cover as follows: No Filters, Anamorphic No Edit, Anamorphic Desqueezed, Wide Angle, Macro

The quality of the filters and the power of the magnets are fantastic(Maybe a bit too strong?). Images still look very sharp and there's minimal color shift between the Macro, Anamorphic, and Wide Angle.

The Anamorphic is able to stack with the other filters, however the Macro and Wide are not without a work around. The Macro and Wide magnets are reversed so they repel the other filters, however if you flip the ND's around and stick them to the Macro and Wide they'll then mount to the Osmo. You will have a slight vignette, but it is something you can fix in editing.

While the magnets are very strong, it also makes the NDs difficult to remove without feeling like you're going to harm the gimbal motors. They all have grooves on the sides that you can hook a fingernail into and pull it off that way, but it still takes a little more force than I care to exert.

Speaking of the NDs, the one you really need is not here. If you're following the rules of shooting video, doubling your frame rate for 30p, and shooting at 1/60th, then you really only need the ND16. ND8 is not strong enough for full sun, and ND32 is a little too heavy. ND16, when ISO is left on 50-3200 auto, will cover you from a dark room to full sun without going above 1800 ISO and without peaking highlights at ISO 50. However, if you prefer to set your ISO at 800 and rely entirely on NDs for your exposure, the heavier NDs will be appreciated. If you're shooting at 24 or 25p then the ND32 might cover you for the full day sun a little better. I just feel like a ND8, ND16, and ND32 would have been better options.

The Macro lens is really nice and opens up so many possibilities with the Osmo. From shooting botanical macros to product, it really is a needed attachment.

Comparing the Wide Angle to the Anamorphic its fairly obvious that you can attain the same dimensions simply by cropping the Wide Angle shot to an Anamorphic ratio. However, if you want to preserve the full dimensions of the 4K then the Anamorphic lens will give you the same overall width FOV as the wide angle lens.

The Wide Angle lens is a few MM wider than the one that comes from DJI in the creators bundle. After shooting with the camera for almost 2 weeks straight for work I have to say the wide angle is not super useful in my use case(Osmo Wide). The inability to properly stack a pro mist and ND without a heavy vignette is a no-go for me. I feel like the stock lens is plenty wide enough, but if you're shooting interiors and don't need a mist or ND then I would say the K&F Wide is the way to go. You have a little more vertical warping, but you'll see a fair bit more of the interior than using the Osmo Wide.

TLDR: Its a great filter set, with some limits, but it will open the door to really get the most out of the Osmo 3
